The snow-flakes began to fall just as they finished the work--the result being a sort of flat-roofed shelter with snow walls ten feet long and six feet high, in front of the tent. A large quantity of firewood was piled up at the entrance to the shelter. "That is a capital idea, Luka," Godfrey said as they retired into the tent. "We can sit with the entrance of the tent open now if we like and get the benefit of the fire outside, for the air having to pass close by it on its way to us gets comparatively warm." When they went out to build up the fire for the last time before lying down, snow was falling steadily, and was already deep in front of the entrance to the shelter. The dogs had been well fed and lay thickly clustered round the fire, evidently greatly contented with the unusual luxury of a roof over them. Godfrey crawled into the tent again, closed the flaps, hung up a skin before them, and getting into his sleeping-bag lay there comfortably smoking his pipe and talking to Luka. "We are as snug here as if we were in a palace, Luka; but I should not like to be caught out in the woods to-night. Have you ever heard of any of the Ostjaks or Samoyedes being frozen to death?" "Couldn't be frozen if they had a hatchet and matches with them," he replied. "Can always chop down branches and make a hut and a fire in the middle to keep it warm. Then snow comes and covers it up and keeps out the wind. Out on the plains a man might get frozen if stupid, but he ought never to be if he knew what to do. He should look for a hollow where the snow had drifted deep, then make a hole in the side of the drift and crawl in. He ought to be quite warm there if furs are good. But they do not often get lost; they never go very far from huts when snow in the sky. Directly it comes on they would make for home. Can always get along in snow-shoes." "The Isvostchiks are often frozen in St. Petersburg in their sledges at night," Godfrey said. "They can't build huts in a town," Luka remarked; "they can't find snow deep enough to get into; town not good in winter." "Are there many wolves here, Luka? Do they often attack people?" "No, there is plenty of game in the woods. In Russia the game now, so I hear, is scarce, so the wolves must take to eating men; but here there is plenty of game, and so they do not often attack people. I have heard of hunters going out and never coming back again. Then people say wolves eat them, but not often so. May be killed by elk, or hurt by a falling tree, or climb hills and fall down. I do not think it is often the wolves. Wolves great cowards." "I am glad to hear it, Luka: I have heard them howl sometimes at night and wondered whether they would come this way." "Not come here," Luka said decidedly, "we keep plenty of big fire. All beasts afraid of fire. Then we have got dogs and guns. Much easier for wolves to attack elk; but even that they seldom do unless it is wounded or has injured itself."
